wow!

 

The biggest that I tried to fit on mine were Twin T3/T4's. But I dont know if they can reach your power goal although I am pretty sure they can.

 

t3's/t4's......hell yeah, its powerfull enough to pump out 500's.( w/ proper internal mods.)

 

Thats what I thought.

 

No need to upgrade the internals, they are fine.

You will need about 650-700 crank hp to get 500 to the wheels.
The questions are, do you want 500 to the wheels on pump? pump + octane booster or intake charge cooler? or on race gas?

If you want it on pump you will be looking at TD05 or T3/T4 turbos.
If your going with TD05 you will need at least EVO 3 16G's, but even then it would be tough, so I would sugest something along the lines of a twin 20G turbos.
If you want T3/T4 I would look into the DR800-DR1200 kits. You would probably need to go with the DR1000's or bigger.
If you run meth or alky with pump you can push a few more psi to make it easyer to achieve the 500whp mark.

Since pump + octance booster(propain) is pretty close to race gas Ill just include it in here.
If your looking at race gas you could stick with the TD04 housings. A few people have achieved 500whp on 13T's, 15G's, DR650's, and 368SX's.
Jumping to a TD05 or T3/T4 turbo makes this even easyer on race gas.

All supporting mods of course.

 

really??[:-] wow.....good info.
